The Coldplay frontman said he felt like he had won the âlotteryâ after the Hollywood star agreed to go out with him and then transformed his fortunes in the bedroom.

Despite his own fame and fortune, Martin said he was a âloserâ before Gwyn sprinkled her Tinseltown glamour his way. In a surprising admission, the Paradise singer revealed he had only ever been in âone serious relationshipâ and added: âIâm in itâ.

The 34-year-old conceded he went from one extreme to another when the pair hooked up at a Coldplay gig in 2002.

After it was pointed out that marrying his first girlfriend a year later was a bold move, Martin said during an interview on US TV: âItâs a big leap? What, from being a loser, to going out with an Oscar winner?â Itâs a giant leap. Letâs face it, itâs like winning the lottery.â

His gooey chat about the actress-turned-Goop lifestyle guru was a rare break from his boycott of sharing the details of their private world.

The pair have long refused to be photographed together in public. But behind closed doors, the English megastar puts his continuing gravy train of chart hits down to raising a family with the 38-year-old.

They live with their children Apple, seven, and Moses, five, in north London. âItâs made it more focused,â he told CBS Sunday Morning.

âAnd you have a purpose. I like what it does, just the idea of having to work hard so your kids are OK.â
